A student decides to move a box of books into her dormitory room by pulling on a rope attached to the box. She pulls with a force of 80.0 N at an angle of 25.0o above the horizontal. The box has a mass of 25.0 kg, and the coefficient of kinetic friction between box and floor is 0.300.
a) Find the acceleration of the box.
b) The student now starts moving the box up a 10.0o incline, keeping her 80.0 N force directed at 25.0o above the line of the incline. If the coefficient of friction is unchanged, what is the new acceleration of the box?
A compressed-air cylinder is known to fail if the pressue exceeds 100 atm. A cylinder that was filled to 20 atm at 22°C is stored in a warehouse. Unfortunately, the warehouse catches fire and the temperature reaches 900°C. What is the pressure ins..
